# Offensive Security Code Review
Analyze the following source code strictly from an offensive security (Red Team) perspective. 
1. Identify missing authorization checks or flawed RLS policies.
2. Spot hardcoded API keys or vulnerable env variables.
3. Check for XSS (Cross-Site Scripting) or insecure DOM insertions.
4. For every vulnerability found, provide the exact severity (Low/Med/High/CRITICAL), an explanation of the exploit, and the exact patched code snippet.
Do not compliment the code. Be ruthless, precise, and paranoid.
